Re: NSAP Addressing

RFC 1629 is helpful.  Particularly the portions regarding Area ID's and
Routing Domain Identifiers, which recommends which bytes to reserve for a
subscriber to address his switches.  I like to assign the NSAPs from the
top of my address space closer to the core of my network, because PNNI
Peer Group Leaders are elected based on having a higher NSAP. 
Consequently, when I summarize for routing purposes, customers get numbers
at the bottom of the "subnetwork" and I use the top addresses first.
